CHURN-CLOSURE FASTENING.

SPECIFICATION forming part. of Letters Patent No. 423,489, dated March 18, 1890.

Application filed October 28, 1889. Serial No. 328,419. (No model.) A

To all whom t may concern:

l Be it known that I, SAMUEL D. PALMER, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Churns, of which the following is a specification.

This invention relates to a class of churns known as the revolving barrel-churn, and in which a bail-fastening is employed to hold the removable head in position on the churnbody.

In the accompanying drawings, Figure 1 is an isometrical representation of a churn embodying my invention in which outside ears are employed. Fig. 2 isan isometrical represent-ation of a churn embodying` my invention in which a ring-head carrying the ears is employed.

The churn shown in the drawings at Fig. 1 consists of a churn proper 1, to which are secured outside ears 2 by a fastening passing through the churn and ears. A ring-head 3 is placed in the chine of the churn and eX- 'tends slightly above the chine to receive the l ling the removable head.

The churn represented at Fig. 2' consists Vof a churn-body 1, in the chine of one end of which is seated a ring 9, with an uprising bead 10, which forms a seat for a packing 4 in the under side of the head 5. From the upper surface of the ring 9 rise ears 13, in which are pivoted bails 6, capable of a swinging movement. These bails when turned inward will rest on the removable head near its periphery, and should a downward pressure be applied to the free ends of the bails a similar pressure would be applied to the removable head, thereby forcing the packing in engagement with its seat.

I have constructed a fastening which does away with any connection of the fastening with the removable head, but which simply reaches from one bail across to the other bail, and in this instance consists of a lever 15, having apivotal connection with one of the bails and of sufficient length to reach across the other bail when the bails are swunginward. A depending arm 16 stands at an angle to the main portion of the lever and has its inner inclined face serrated or notched.

Vhen it is desired to depress the bails for Vthe purpose of pressing the head to its seat on the churn, the bails are' swung inward onto the head and the lever is swung across the bails, so that its depending arm will engage the outer surface of the bail. By reason of the inclination of the depending arm its extreme end will come first in contact with the bail, and by pressing downward on the lever the depending ar'm will descend notch by notch until the required pressure is brought to bear 0n the removable head. By the downward pressure of the 'lever the free ends of the bails are brought closer together, and are thus held by the lever-connection. An operating-handle 17 furnishes means by which the lever can be released from its engagement with the bail. This arrangement furnishes a cheap and eflicient means for securing the head of a churn in position on the body of the churn.

' I do not limitmyself to the use of my fastening in connection with the churns herein shown and described, as it is evident that many varieties of bail-ohurnsare and may be produced in which myimproved fastening could be applied.

I claim as my invention-f;

1. The combination, with a churn, of Va removable head, a pair of bails for holding the head in posit-ion on the churn, and a fasteningprovided with an arm having its inner face inclined and notched, the said fastening engaged at each. end with said bails,substan tially as set forth.

2. The combination of a churn, a removablehead, a pair of bails holding the head in vided with serrations or notches to receive Y the bail, substantially as set forth.
